Bus plunges into ravine in north China, killing 10

BEIJING 
A tourist bus has plunged off a highway into a ravine in northern China, killing at least 10 people.

The official Xinhua News Agency says the accident happened Saturday morning when the bus, carrying 33 people, crashed on a highway in Shanxi province. Xinhua says the bus was not full, but did not immediately give any further information.

Road safety is a serious problem in China, with many accidents caused by poorly maintained roads and bad driving habits.
